I had not seen the word TDU in forever. As a tech writer I got to go down and watch them overhaul a TDU. All I could think was wow when they had to torque bonnet on the the body. I don't remember the foot pounds required but there were two sailors in the hole cussing up a storm trying to get the torque converter on the nut and still have room to move. Made me glad I was a Hull Tech.My other favorite job to watch was when they replace the seats on the BFV valve.
A TDU in sub-talk is a Trash Disposal Unit. A Teflon-coated ball valve at the bottom of a vertical tube running up into the Ops compartment near the galley. Armored upper hatch as a second pressure boundry. Single-point-of-failure of the pressure hull when in use; very dangerous.
You could work on the ball valve in drydock, but you'd be outside. The tube was about 18 inches in diameter, so nobody was working inside it. Which makes me think you're talking about some other kind of TDU.
What's a BFV valve?

I am not sure now what it was they were working on. I just remember looking down into a hole and the two guys trying to get those nuts torgued. I seem to recall the divers had to put on belly bands before they could work on the valve.
BFV (the MM's called them big f'n valves) can't remember their correct name. I think they were only on the 608's and 616, and maybe the 627's. I don't remember them being on the 637's or other fast attacks. They apprently were never needed but since it was on the boat it had a PMS card so a check was required. The test required cycling the valve which destroyed the seats every time because of the crud built up on the ball itself.
Sitting here thinking about it, wow that was a long time ago....... I am starting to feel pretty old. [;)]

All I can think of is the DCT tanks for hovering. But those valves were used almost every day.

I think it has to do with the missile tubes.
